Hi Thierry,

WR133 (HIP99002, HD190918) is very close to this location (11 arcsec) and much brighter at Vmag 6.7 compared with 9.7

Is there any possibility that this is the wrong star or there is some contamination?

Hello Francois.

Your perfectly right ! The algorithm of guiding put the wrong star is ne slit.
I need to improve my program to manage this kind of situation. Today i need no brighter star close to 15 arcsec of the target.
